Flink iterations
WebRegisters an Aggregator for the iteration. Aggregators can be used to maintain simple statistics during the iteration, such as number of elements processed. The aggregators compute global aggregates: After each iteration step, the values are globally aggregated to produce one aggregate that represents statistics across all parallel instances. WebThe DeltaIteration represents the start of a delta iteration. It is created from the DataSet that represents the initial solution set via the DataSet#iterateDelta(DataSet,int,int...) method.

WebJan 4, 2024 · When scheduling tasks, Flink needs to iterate over all the connections between result partitions and consumer vertices. In the past, since there were O (n 2) edges in total, the overall complexity of the iteration was O (n 2 ). Now ExecutionEdge is replaced with ConsumerVertexGroup and ConsumedPartitionGroup. WebStreaming Analytics # Event Time and Watermarks # Introduction # Flink explicitly supports three different notions of time: event time: the time when an event occurred, as recorded by the device producing (or storing) the event ingestion time: a timestamp recorded by Flink at the moment it ingests the event processing time: the time when a specific …
WebAug 13, 2024 · I'd like to write a Flink streaming operator that maintains say 1500-2000 maps per key, with each map containing perhaps 100,000s of elements of ~100B. Most records will trigger inserts and reads, but I’d also like to support occasional fast iteration of entire nested maps.
